International Comfort Products T9MPV050F12B1 Air Pressure Switch
The main job of an air pressure type switch is to see if the blower fan is actually running. This switch is one of the critical devices designed to stop injuries or explosions. The vast majority of pressure switches made today may have a reset feature that is manual, which means it would need to be reset in order for the HVAC system to continue running.
How do you Know when the HVAC Air Pressure Switch is Going Bad
- The correct temp is almost never reached.
- Your furnace can't run.
- Wrong electrical voltage reading from the switch.
